Question about Akai PT4298HD Rear Projection Television

Blue Line Our TV is three years old. All of a sudden it has a fairly large blue line running vertically down the center. We have no idea what this is or how to go about fixing it. Is this a repairable problem? The only thing we know about projection tv is that we have heard bulbs got out. Does this problem sound like a bulb issue? Appreciate any and all information. Thanks.

I have the very same issue, except for me it is a red line. The line looks like a permanent magic marker line on the backside of my screen. There is also a small drop at the top of the screen above the line. The line is perfectly in the center from left to right. I have been told by others that it may be an "overlap" issue which can be adjusted. It was after replacing the convergence board that the problem came about. I have tried two new convergence boards and the problem still persists. Is this something that can be adjusted? Do I need to get a calibration DVD to help me through? Any ideas?

Sorry no bulb issue here. theres a vertical sweep issue though. if your not a tech i wouls sugest that you find a good one as this is a solid state set and there are no user replaceable parts inside, so you cannot service yourselfs unless your trained to do so. please seek out a trained tech to assist you in this repair.

if this tv is older than 5 years it may need to refill the liquid on the proyection bulbs and/or could have contaminats in the fluid causing the ghost and to fix that you will need a professional person to do it

I have a vertical blue line....left of center

If it is narrow you have a dead pixel problem. If so contact HP for advice. Three year warranty on screens and they usually swap out for failures. Very common problem.

Vertical, pencil-thin blue line appears after 10 minutes of viewing (any source)

I would suspect a connection breaking down as the set heats up. A shop will probably have to put the set in a stand to hold it while they check for loose connections or defective components inside. Not a DIY job by any means. If this line went completely through the picture either vertically or horizontally and stayed there then this would have indicated a failure in the Panel itself. A thin Line any where on the screen consisting of one pixel in width is a Panel Failure according to Hitachi.

Akai tv PT4298HD wont turn on. Only timer light turns on. I unplugged my tv when the picture went off and to a static snow screen. We unplugged it and plugged it back in, when we turned it back on all that came on was the timer light.

AKAI PT5492 no power - only timer comes on My AKAI PT5492 rear projection TV has been working fine since 2001 and yesterday, without warning, it would not turn on. The timer light did go on and will now not go off. In addition, there is a clicking sound every few seconds. I unplugged the unit until I can determine what to do. Thanks- -Fred
